The Danish municipal elections 2025 have left the Social Democrats as the largest party in votes, but handed Venstre the title of Denmark’s biggest mayoral party and produced a map full of local power shifts, from Copenhagen to small island councils.
Venstre becomes Denmark’s largest mayoral party
Measured in votes, the Social Democrats (Socialdemokratiet) still top the national scoreboard with around 23.2 percent of the vote and roughly 599 council seats, even if that represents a loss of more than five percentage points and over 150 mandates compared to 2021. Venstre follows with about 17.9 percent and just over 520 seats, while the Conservatives remain the third‑largest party nationwide.
But in Danish local politics, mayoralties (borgmesterposter) matter as much as vote share. On this front, Venstre has overtaken the Social Democrats. On Wednesday morning, the liberal party was on course for around 39 mayors, compared to about 25–26 for the Social Democrats, while the remaining posts were still being settled in late‑night negotiations. Even if the final numbers shift slightly, the direction is clear: Venstre has become Denmark’s largest mayoral party, a symbolic reversal of the traditional balance between the two big governing parties.
The new picture reflects a series of local breakthroughs. Venstre has taken over town halls in long‑standing Social Democrat strongholds such as Næstved, Køge, Holstebro, Furesø and Frederikssund, often after decades of almost uninterrupted red leadership. In several of these municipalities, Social Democrat vote shares have fallen by more than ten percentage points, clearing the way for blue mayors supported by Conservatives and other centre‑right parties.
A historic Social Democrat meltdown across the map
In a separate NordiskPost article we look in detail at how the Social Democrats lost Copenhagen after 122 years and saw their number of mayors nearly halved. The national picture confirms the scale of that setback.
Across 89 of Denmark’s 98 municipalities, the Social Democrats have recorded losses. In some provincial towns such as Fredericia, Holstebro, Skive, Lolland, Favrskov and Aabenraa, the party has dropped by double‑digit margins, in places close to twenty percentage points. In Frederikshavn, a traditional stronghold, the party has lost its absolute majority and no longer holds the mayoralty. On the Copenhagen urban fringe, municipalities like Brøndby, Gladsaxe and Albertslund show the same pattern of shrinking red majorities.
In two small island municipalities, Fanø and Læsø, the Social Democrats have disappeared from the council altogether. For the first time since the 2007 municipal reform, the party is no longer represented in all of Denmark’s municipalities. For a party that has built its identity on being present “everywhere in the country”, the symbolic impact is considerable.
Commentators have described the 2025 elections as a “meltdown” for the Social Democrats at local level. The party has now lost ground in big cities, market towns and rural municipalities alike, and can no longer rely on its old network of mayors to anchor national support. The test for the leadership will be to understand whether voters are reacting primarily to local issues – from hospital reforms to school closures – or sending a broader signal about the course of the national government.
SF, Conservatives and new parties seize local opportunities
The story of the Danish municipal elections 2025 is not only about the Social Democrats’ losses and Venstre’s gains. Other parties have also used the opening created by voter dissatisfaction to strengthen their position in local politics.
On the left, SF (the Socialist People’s Party) is one of the clear winners. As we explore in a separate article on Copenhagen, SF has taken the lord mayoralty (overborgmesterpost) in the capital with Sisse Marie Welling at the head of a broad coalition. Outside Copenhagen, SF has picked up mayoralties in municipalities such as Gladsaxe and Lejre, often combining green priorities with social policies that appeal to traditional Social Democrat voters.
The Conservatives (Det Konservative Folkeparti) have also made visible gains, particularly in Zealand and parts of Jutland, and now hold more mayoralties than after the last elections. In places like Hillerød, Egedal and several medium‑sized towns, conservative candidates have managed to build broad coalitions around promises of sound finances, business‑friendly policies and stable administration.
On the right‑wing flank, Danmarksdemokraterne, contesting their first municipal elections, have entered many local councils and in some municipalities reached double‑digit support. While they have so far secured only a single mayoralty, the network of local councillors gives the party a broader organisational base ahead of the next parliamentary election. That mayor’s chain goes to Mads Fuglede in Ringkøbing–Skjern, where Danmarksdemokraterne became the second‑largest party with 21.7 percent of the vote, behind Venstre on 26.5 percent. Liberal Alliance has also converted niche urban support into at least one mayoral chain, even if the party’s overall local presence remains modest.
Taken together, these shifts confirm that Danish local politics is becoming more fragmented, with several parties capable of winning mayoralties where they present strong local candidates and clear profiles. The three traditional “mayor parties” – Social Democrats, Venstre and Conservatives – still dominate, but they now compete with greener and more populist alternatives for influence in city halls.
Blue and red blocs almost tied nationwide
The elections were also the first municipal test for Moderaterne and Danmarksdemokraterne. Danmarksdemokraterne enters the local level with around 123 council seats, while Moderaterne wins six mandates nationwide. Together with its first mayoralty in Ringkøbing–Skjern, this gives Danmarksdemokraterne a much broader platform than its short history would suggest.
If voters are grouped into traditional red and blue blocs, the balance is almost even. Venstre, the Conservatives, Dansk Folkeparti, Liberal Alliance, Danmarksdemokraterne, Kristendemokraterne and Nye Borgerlige jointly receive about 47.3 percent of the vote, while Socialdemokratiet, SF, Radikale Venstre, Enhedslisten and Alternativet together reach roughly 47.9 percent. Commentators note that, even if municipal elections differ from parliamentary races, this near‑parity and the recovery of the classic blue parties constitute a psychological boost for the V/K axis and for the broader centre‑right opposition.
Local results feed into national tensions
The outcome of the Danish municipal elections 2025 will quickly feed back into debates at Christiansborg, where the tripartite SVM government of Social Democrats, Venstre and Moderates has already faced voter scepticism. For Venstre, the strong showing in mayoralties is likely to embolden voices who argue that the party’s natural alliances lie in the blue bloc rather than in a centrist coalition with the Social Democrats.
Analysts point out that Venstre’s local campaigns often highlighted classic centre‑right themes such as local businesses, agriculture, infrastructure and proximity to citizens. The question inside the party will be whether these priorities should be reflected more clearly in national policy, and whether participation in the SVM government blurs Venstre’s profile for its core voters.
For the Social Democrats, the challenge is even sharper. Prime minister Mette Frederiksen has already acknowledged that the setback is deeper than expected and has taken personal responsibility for the result. She not only leads the national government, but also encouraged former minister Pernille Rosenkrantz-Theil to run in Copenhagen – a gamble that has now ended with the loss of the capital and a long list of local bastions.
Yet the picture is not uniformly bleak. Social Democrat mayors have defended their positions in several large cities, including Aarhus, Odense, Aalborg and Frederiksberg, showing that the party can still mobilise support where local leaders are seen as competent and trustworthy. These pockets of strength will be important bases from which to rebuild.
The 2025 municipal elections thus leave Danish politics with a more complex local landscape: Venstre stronger in the town halls, Social Democrats wounded but still largest in votes, and a group of medium‑sized and new parties testing how far their influence can reach. How these results are interpreted in the coming months will help determine not just the priorities of local councils, but also the tone and alliances of the next national election campaign.
